IntelliJ IDEA 2021.2 introduces Project‑Wide analysis, enhanced code formatting, a revamped package search, richer inspections, improved Markdown support, smarter version‑control actions, JavaFX wizard updates, and numerous UI and performance refinements for a smoother development experience.

Project‑Wide analysis lets you track errors across small‑to‑medium projects before compilation (available in IntelliJ IDEA Ultimate).
When saving a project, automatic actions such as code reformatting and import optimization can be configured via Preferences/Settings | Tools | Actions.

Editor
Inspection descriptions and quick‑fix suggestions are now more comprehensive, with usage examples.

Project copyright notices now include the creation year and the current version year by default.
Improved Markdown support: convert .md files to various formats, configure image sizes, drag‑and‑drop images, fix list formatting, and add a floating toolbar.
User Experience
Open local Eclipse projects directly from a dedicated folder on the welcome screen; IntelliJ IDEA auto‑detects such projects.
